CONNECTING DEVICE.

Application filed ,luly 14, 1917. Serial No. 180,628.

To all whom it may concern:

Be it known that I, NICHOLAS FURDUY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Connecting Devices, of which the following is a specification.

My invention consists of an improved connecting device, and is particularly adapted for use on flexible hose. One object of my invention is to provide a device which can be used for connecting the end of a hose to a valve or coupling member.

Another object is to so construct my invention that it can be quickly and easily attached to a hose and will not become loose during the use of the hose.

A further object is to make my improved connecting device of simple and durable construction and so that it can be manufactured and sold at a low cost.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure l is an outside view of the end of the hose having my improved connecting device attached thereto. V

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is an outside view of a tube and separate collar which form a part of my invention. i

Fig. 4 is a longitudinal section of a modified form of the tube shown in Fig. 3 and in which the collar is made integral therewith.

Referring to the drawing, 1 is a tube preferably made of metal and at one end is provided with external screw-threads 2. A collar 3 is internally screw-threaded and adapted to be screwed on the threads 2 of the tube 1. This collar is preferably made of metal and has a flared or cam surface 4 which extends from one end.

The external diameter of the-tube 1 is substantially the same as the diameter of said end of the collar from which the flared portion 4 begins. The opposite end 5 of the collar 3 extends substantially at right angles to its longitudinal axis and is preferably rounded as shown at 6 at its intersec- Specification of Letters Patent.

Patented May tion, with the flared portion 4 so that there are no sharp corners projecting from the collar 3.

A nut 7 is designed to be screwed upon than the exterior diameter of the hose 10 to which the device is attached so that the extreme end portion of the hose can be extended within the recess as clearly shown in Fig. 2, the tube 1 and collar 3 being positioned within the hose so that only a portion of the threaded end 2 of the tube projects out of the end of the hose. Y

When it is desired toattach my invention to a hose, the smooth end 11 of the tube 1 is pushed within the hose, suflicient force being applied to spread the hose sufliciently to permit the collar 3 to be pushed slightly beyond the end of the hose. This can easily be done for the reason that the tapered portion 4 of the collar will gradually spread the end of the hose to permit the .widest portion of the collar to pass therein. The

nut 7 is then screwed on the threaded end 2 of the tube 1 until the extreme end 12 of the hose engages the inner surface of the recess, and as the latter tapers to a diameter smaller than the normal exterior diameter of the hose, the end of the hose will be compressed and will bend around the end portion 5 of the collar 3, thereby preventing relative longitudinal movement between the hose and the tube.

The farther the nut 7 is screwed on the tube 1, the more the end 12 of the hose will be compressed, since as above stated the oons'erno tion shown in 3. so 3 inclusive, and ll have thereiere given simile? eerie eorresponcling reference nnmeinls,

The soreW-threededl portion 2 of 'lhe tube is made snficiently long 'shel, after she dervice has been etteehecl is she hose a session of the threaded and of the will project heyoncl the nut and portion can be utilized to seome hose he any coupling cleviee desired.
